Abstract
The use of space-angle intensity moments in description and characterization of a paraxial laser beam with small-scale inhomogeneities of its transverse shape is presented. The connection between the moments and customary beam characteristics is discussed. The equations of moments evolution in lens-like optical media with small-scale scattering inhomogeneity are derived and analyzed, on the basis of which some recommendations for fast and suitable medium parameters determination are made.
